ALIGNING DEVICE FR FLASKS.

Application filed December 1G, 1921.

To all whom t Amay concern Be it known that l, llTiLnY T. RABUN, a citizen of the United Sta-tes, residing at Huntington Park, county of Los Angeles, and State of California, have invented a certain new and useful Aligning Device for Flasks, of which the following is a specification. j

My invention relates to molds or flasks as used in founding and has especial reference to a means for aligning the sections of 'liasks of either the tight hingeless form or the snap hinged form or combinations of them and maintaining them in position of alinement or adjustment.

One of the objects of this invention is to provide a simple device for accomplishing the quick and accurate correspondence of the flask sections with one another or with each other, where three or more sections are involved, in which the major portion of the parts thereof may be cast and used as cast without the necessity for machining them or any of the co-operating parts, whether cast or otherwise produced.

Another object of the invention is to provide a simple, economical and efficient contrivance of this character which is readily adjustable, easily adaptable to all forms of flasks and by which all slack may be taken up, whereby upon removal of the one section from the other, the sand will not remain upon or adhere to the pattern, nor the sand mold or form be injured or disturbed by any unsteady, jerky or unalined removal. of the cope from the drag.

These and other objects are attained by the preferred form of device illustrated in the accompanying drawing, in which- Fig. 1 is a front view of the device showing a plate attached to the cope of a flask and a plate attached to the drag with the contained adjusting mechanism for engaging the pin carried by the cope-plate, the pin being shown partly in dotted lines.

Fig. 2 is a vertical section on line a02-m2, Fig. 1.

Fig. 3, is a bottom plan view of the adjusting mechanism contained on the underside of the plate, fastened to the drag, showing also the pin of the cope-plate in position.

Fig. 4: is an end view of the follower member.

Fig. 5 is a plan view of a follower member formed with an orifice for a` round pin.

Serial No. 521,366A

F ig. 6 is a plan view of a follower member formed with a square opening for a square pin, and

F ig. 7 is a plan view of a follower member formed with an open end for accommodation of a round pin and adapted for use for either a tight, hingeless or a snap, hinged flask or combinations of them.

rlhe invention comprises two plates 1 and 2, respectively fastened in any suitable manner to the cope A and drag B, of a mold or flask.

The plate 1 is provit ed with an apertured boss 3, for accommodation of the re duced threaded end 4C of a pin 5, which is held in association with the plate 1, by a nut 6 or other means suitably adapted 'to the purpose. Where a square or rectangular pin shank is used, suitable lugs 7 may be provided, preferably by casting same integral with the bottom of the 'plate 1, to prevent the pin from turning and becoming loose.

The plate 2 of the drag B is formed with a substantially inverted elongated il-shaped portion, whose upper apex 8 is flat. for purposes to appear hereinafter. This v -shaped surface occupies approximately the central surface of the plate 2, and is slotted inwardly from the end, seen at 9, the sides 10 forming the slot, inclining from opposite sides and forming slideways 11 for a follower member 12, held in place and arranged to travel between flanges or rails 13, cast integral with the sides 10. The wall forming the rear of the slot is l/-sliaped as shown in Fig. 1, for accommodation of the pin 5, but may be Of any other shape to answer particular needs. lThe follower member 12, aforo referred to, is movable along' the slideways 11, to engage the pin for adjusting the cope, by which it, (the pin), is carried, by a key or wedge element 14, which fits in a keyway 15, in the follower member and flanges or rails 13, as shown in Fig. 3. rlhis key or wedge element le is provided with an elongated slot 16 and the follower member 12 and the fiat surface S of the plate 2, are also provided with slots 17 and 18, respectively, for accommodating a bolt 19, by which the parts are locked in intimate association, after the adjustment of the follower member to the pin is effected.

lt will be seen that the upper faces of the follower members, represented in Figs. 1i,

5, 6 and 7, are V-shaped on the upper surface and conform to the shape of the V- shaped portion of the plate 2 and are plane on the underside. The members, as shown in Figs. 5, 6 and 7 are interchangeable with the follower member shown in Figs. l, 2 and 3. It will be understood that the pin and plate mechanism described, is provided on two sides or ends of the flask and that it is susceptible of use with the tight, hingeless variety of liaslrs, the snap, hinged type or combinations of them.

What l claim, is:

l. A Hasi: composed of sections, a plate fastened to one of said sections and supporting a vertical pin, a plate fastened to the other of said sections and formed with a. slot to accommodate said pin, the under member relatively to said pin and on the under side of said plate, and armeans to connect said wedge and follower member.

2. In a flask composed of sections, a plate ,fastened to one of said sections and support ing a Vertical pin, a plate fastened to the other of said sections and formed with an inwardly extending slot to accommodate said pin, the under faces of the sides forming said slot inclining to the horizontal and constituting a slideway, said sides formed with downwardly extending flanges providing a guide, a follower member slidable on the under side of said slideway and having a cut-out portion and an elongated opening, laterally of and in the cut-out portion of said follower member to more the said follower member relatively to said pin, and a means extending through said follower member and wedge to lock same in position of adjustment.

In testimony whereof I have set my hand.
